◍ Feathers initially evolved for flight..
Answer: False
◍ T/F There are more bird species than mammalian species in existence
today..
Answer: True
◍ List two organs contained in the abdominal cavity..
Answer: The abdominal cavity contains the stomach, intestines, spleen and
liver
◍ Archaeopteryx had a long boney tail..
Answer: True
◍ One in 4 bird species is considered to be at a high risk for extinction..
Answer: False
◍ The arboreal hypothesis for flight suggests flight originated by early birds
running from predators and thus taking off like an airplane to initiate flight..
Answer: False
◍ True or False?a. Cellular respiration occurs in the mitochondria. (T or F) b.
The purpose of cellular respiration is to produce AT
P. (T or F) c. Integral proteins are only found on the inner surface of a cell
membrane. (T or F) d. Endocytosis is the process that occurs to eject
biomacromolecules from the cell. (T or F)e. Pinocytosis uses a signaling
molecule from another cell, binding to the cell membrane to bring about
changes within the cell proteins. (T or F).
, Answer: a. Trueb. Truec. Falsed. Falsee. False
◍ A bird is an animal that can fly..
Answer: False
◍ Theropod dinosaurs had solid bones and laid eggs..
Answer: False
◍ You are observing two cells under the microscope. They are the same type
of eukaryotic cell but one appears much larger. Based on appearance alone,
which one would you expect to be carrying out respiration at a more active
rate, the larger or smaller cell? Explain why..
Answer: I believe it is the smaller cell that will breathe at a more active rate
because in order for respiration to occur efficiently and more actively the
surface area to volume ratio is very critical; also, if the larger surface area is
present then the diffusion of gases occur at a higher rate; so, larger cells will
have a smaller surface to volume ratio and diffusion that will occur at a
slower rate creating a less active respiration; and, on the other hand smaller
cells will have a larger surface area to volume ratio and an improved
diffusion rate, so the higher rate and more active respiration.The smaller
cell. Cells need to remain relatively small because as a cell expands the
amount of surface area relative to the volume of the cell decreases. The
smaller cell is more active because relative to its volume, its surface area is
larger than a bigger cell. With a larger surface area (relative to its volume)
this allows the metabolic processes to occur faster.
◍ Global warming is not expected to impact the population of penguins..
Answer: False
◍ Note: Essay answers must clearly be in your own words.Explain what
happens to the epiglottis during swallowing. Why?.
Answer: During swallowing the epiglottis moves inferiorly to close off and
prevent aspiration by covering the trachea and creating a passage for liquid,
food, or bolus into the esophagus; and, preventing these things from entering
into the lungs.
, ◍ Air and food pass in which one of the following areas:.
Answer: Oropharynx
◍ Overall, the population trend for birds is.
Answer: decreasing
◍ Based on fossil evidence, what is the name of the first bird with a horny
beak?.
Answer: Confuciusornis
◍ Label the following five items from the diagram:Label B-
___________Label D- __________Label E- __________Label F-
__________Label G- __________.
Answer: B - Oral CavityD - EpiglottisE - GlottisF - TracheaG - Esophagus
◍ From widest to narrowest, the branches of the bronchial tree are:.
Answer: Primary bronchi, secondary bronchi, tertiary bronchi, bronchioles
◍ The whooping crane is not an endangered bird species..
Answer: False
◍ Birds likely evolved from theropod dinosaurs..
Answer: True
◍ When two unrelated species end up looking the same physically this is
called?.
Answer: convergent evolution
◍ Animal species considered dangerous by humans are predisposed to
endangerment..
Answer: True
◍ Explain why someone who has hypergastrinemia (excessive secretion of
gastrin) might develop gastric/stomach ulcers..
Answer: Hypergastrinemia leads to excess secretion of the gastrin hormone,
which induces excess secretion of hydrochloric acid in the stomach; and, the
excess acid then acts as a protective mucousa layer causing disruption that
can lead to those ulcers.Gastrin stimulates the secretions of pepsinogens and
